Glucosamine upset my dog's stomach, and so I had been giving him straight HA. But I decided to try this as it works great on my horses...it has smaller molecules that are supposed to be able to synthesize glucosamine in the body, as well as anti-inflams and HA all together in one tiny dose.

It works great for my little chi! He is bright and bouncy, no "bump" on his spine from his injury, and this 8 oz will last forever! I recommend giving it a try.
